Adam is asked to construct the bisector of ZR. Explain the error in Adam's work. R
Х
Choose the correct answer below.
O A. Adam changed the setting of his compass at some point during the construction, making his bisector incorrect.
OB. Adam started the construction at the wrong place. He should have started at point R and drawn an arc that intersects both rays.
O C. Adam didn't draw a third arc to verify that the second point on the bisector was correct.
OD. Adam started the construction on the wrong ray. He should have started on the other ray

A

Step-by-step explanation:

He didn't put a arc on both sides of the line.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

something over 10 so ? /10
